Abstract

Salah satu perusahaan yang bergerak dibidang manufaktur baja adalah PT. Zenith Allmart Precisindo (ZAP). Namun pada proses produksi casing pompa Tipe X terjadi reject yang melebihi batasan perusahaan. Reject pada bulan Februari mencapai 3,2% (level sigma 3,35). Padahal batasan reject hanya 2% (level Sigma 3,55). Selain itu sistem pengukuran visual masih belum diketahui kapabilitasnya. Penelitian ini bertujuan menganalisis kapabilitas proses produksi serta level sigmanya dan kapabilitas sistem pengukuran menggunakan metode six sigma yang didalamnya terdapat metode kappa statistik. Setelah dilakukan analisis terhadap data inspeksi visual terhadap produk pada Maret dan April 2015 diperoleh hasil bahwa sistem pengukuran inspeksi visual di PT. ZAP sudah kapabel untuk masing-masing hasil within appraiser dan between appraiser. Hal ini menandakan bahwa sistem pengukuran visual tidak memerlukan perbaikan. Level Sigma dari proses produksi casing pompa tipe x secara keseluruhan di PT ZAP adalah 3,65 yang artinya terdapat 15647 produk cacat dari 1 juta produksi casing pompa tipe x. Jenis defect bocor menjadi jenis defect yang paling sering dijumpai di dalam area produksi Dipping. Area produksi tersebut memiliki level sigma terkecil yaitu hanya 3.25. Hal-hal yang paling berpengaruh terhadap jenis defect bocor adalah cetakan keramik kurang tebal dan bahan campuran yang kurang sesuai dengan spesifikasi.

One company that is engaged in the manufacturing of steel is PT. Zenith Allmart Precisindo (ZAP). But in the process of production casing pompa X type occurs reject that exceeds the limits of the company. Reject in February reached 3.2% (3.35 sigma level). Whereas restrictions reject only 2% (Sigma level 3.55). Besides the visual measurement system is still unknown capabilities. This study aims to analyze the production process capability and level measurement system sigmanya and capabilities using the method in which there are six sigma kappa statistical method. After analyzing the data a visual inspection of the product in March and April 2015 showed that the visual inspection measurement system in PT. ZAP has been capable for each outcome within and between appraiser appraiser. This indicates that the visual measurement system does not require repair. Sigma level of the production process casing pompa type x overall in PT ZAP is 3.65, which means there are 15 647 defective products than 1 million production casing pompa type x. Type defect leaking into the type of defect is most often encountered in the production area Dipping. The production area has the smallest sigma level is only 3:25. The things that most influence on the type of defect leaking is less thick ceramic mold and mixed materials that are less in accordance with the specification
